Question

Find the mole fraction of solute in its 2 molal aqueous solution.

Answer 1

No. of moles of solute $=2$

Mass of solvent $=1$ $kg$

Since it is an aqueous solution, thus the solvent must be water.

Moles of solvent $=\frac{1000}{18}=55.5$ $moles$

Mole fraction of solute $=\frac{2}{57.5}=0.0347$
